Design of New Catalysts for Methanol Synthesis from syn gas:
We are partner in a European Commission Framework 7 NMP-2013-LARGE project, BIOGO, in which our role is to use first principles DFT simulations to design new catalysts compositions for synthesis of methanol from syn gas, and also examine the synthesis of higher alcohols. BIOGO runs from 2013 - 2017.

Metal Oxides in Renewable Energy Applications. We held a Science Foundation Ireland Starting Investigator Grant (SIRG) "Engineering Metal Oxide Interfaces for Renewable Energy Applications (EMOIN)", from 2009 - 2014, in which we successfully demonstrated that metal oxide heterostructures composed of a nanscale metal oxide cluster adsorbed on TiO2 surfaces (rutile and anatase) are potentially interesting visible light active photocatalysts.
A number of heterostructures have been investigated, among which TiO2 clusters adsorbed at rutile (110), FeOx clusters also adsorbed at rutile (110) and CrOx clusters adsorbed at rutile (110) show reduced band gaps compared with pure TiO2, which will induce visible light absorption. The heterostructure also allows for charge separation upon light excitation, thus making these structures potential visible light active photocatalysts. A collaboration with Prof. H. Tada in Japan throughout this project, lead to successful synthesis of many oxide nanocluster-modified TiO2 systems, and showed excellent agreement between the calculations and the experiments.
A Science Foundation Ireland funded US-Ireland R &D Partnership program project together with University of Ulster (Tony Byrne) and Northwestern University (Kimberly Gray) runs from September 2014 - August 2017. We are aiming to design photocatalysts to activate CO2 for production of useful fuels/chemicals, building on our successful SIRG project and working directly with experiment. Also of interest are water splitting (modelling water oxidation) and H2 splitting, to allow hydrogenation.

Metal Oxides in Renewable Energy Applications. We recently finished a Science Foundation Ireland Starting Investigator Grant (SIRG) "Engineering Metal Oxide Interfaces for Renewable Energy Applications (EMOIN)", in which we investigate metal oxide heterostructures composed of a nanscale metal oxide cluster adsorbed on TiO2 surfaces (rutile and anatase). A number of heterostructures have been investigated, among which TiO2 clusters adsorbed at rutile (110), FeOx clusters also adsorbed at rutile (110) and CrOx clusters adsorbed at rutile (110) show reduced band gaps compared with pure TiO2, which will induce visible light absorption. The heterostructure also allows for charge separation upon light excitation, thus making these structures potential visible light active photocatalysts. A collaboration with Prof. H. Tada in Japan, who synthesises these systems, shows excellent agreement between the calculations and the experiments.
In a follow-on to this project, we have started an SFI US-Ireland project with University of Ulster and Northwestern University to study CO2 reduction on surface modified TiO2.
Electronic Structure of Ceria. Since 2003, we have been applying DFT to the study of the electronic structure of reducible metal oxides, primarily cerium dioxide and titanium dioxide. For ceria, we provided the first consistent description of the reduced surfaces (in which an oxygen vacancy is present) whereby reduced Ce3+ ions are formed, which are notoriously difficult to treat with standard DFT approaches. The dependence of the reactivity on surface structure, as measured by the oxygen vacnacy formation energy, has been investigated. We have also presented a number of studies in recent years on the eletronic structure of doped ceria (in which Ce ions are substituted for another metal cation, e.g. Ti, La or Pd) and investigated the effect of this on the reactivity of ceria.
Reactions at Ceria Surfaces. We have explored the adsorption of small molecules such as CO and NO2 at oxidised and reduced ceria surfaces, both undoped and doped. Our work on the adsorption of both molecules at different ceria sufaces clarified for the first time a number of important points, including (i) the effect of surface structure on reactivity: CO only physisobrs at the (111 )surface, both chemisorbs, forming a carbonate, at the (110) and (100) surfaces, (ii) once Ce3+ ions are present, NO2 will react strongly, with charge transfer from the reduced surface to the molecule, with dissociates, (iii) doping othe surface, especially (111), can be used to enhance CO oxidation, buth without harming NO2 reduction
